Here the length converter starts from kilometres and reports miles. The mile figure, the formula and a table of other length units follow what you type, and swapping the units shows the reverse calculation.
Miles are kilometres divided by 1.609344. One kilometre is about 0.621371 mi, so 5 km is about 3.107 mi and 100 km is about 62.14 mi. Divide by the exact factor rather than multiplying by a rounded 0.62. For the other way round, see miles to km.
